The structure of LSTM and GRU. (a) LSTM. (b) GRU. xt is input. ht and ht−1 are the output of the current cell and previous cell. In (a), it, ft, and ot are the input, forget, and output gates, respectively. ct−1 and ct denote the memory cell and the new memory cell content. In (b), rt and zt are the reset and update gates, respectively. h̄t is the pending output.
